Title: Waste disposal process.
Inventor: WOLF BERND MICHAEL
IPC: A62D3/40
Filed: 1990-10-06
Abstract: In a process for the disposal of toxic and/or infectious waste, especially highly halogenated solids, plastic containers, hospital waste and the like, to recover useful substances and render inert non-recyclable and unoutgassable residues, outgassing by the pyrolytic process is used, with air excluded and a reduced oxygen content, followed by the direct incineration of the distillation gases obtained from pyrolysis or their cracking to form a pyrolysis separation gas. The waste to be disposed of is inserted in an autoclave (2), partially outgassed there for a period of 20 minutes to 6 hours at about 250 to 320 C in an initial outgassing stage, then cooled and made into a granulate or pellets measuring from 1 to 50 mm, which are subsequently treated by the pyrolysis outgassing method in a second outgassing stage at a temperature of 550 to 600 C. This generates distillation gas which is separated from the residues, like carbon, ash, heavy metal particles and other components. The liquid partial outgassing intermediate products, like oil and/or coal tars, produced in the autoclave (2) are taken to the second outgassing stage, while the distillation gas separated off in the first outgassing stage in the autoclave (2) is taken off and added to the stream of distillation gas from the second outgassing stage.

Abstract: Ensemble de cathéter intra-cranien commandé par moniteur, comprenant un cathéter (70, 72) à deux passages, destiné à contrôler la pression intra-cranienne par l'intermédiaire d'un détecteur (76) de pression situé dans un passage, tout en drainant simultanément du liquide céphalo-rachidien par l'autre passage (72, 66). Ledit détecteur (76) de pression est, de préférence, un détecteur à modulation spectrale communiquant avec un appareil de photo-détection, au moyen d'une seule fibre optique (98), réduisant ainsi au minimum le diamètre du cathéter. Ledit photo-détecteur est à auto-correction d'erreurs de signaux provoquées par un changement de température, des changements d'intensité de la lumière d'entrée, et des pertes de transmission dans l'appareil optique. De plus, ledit photo-détecteur coupe la tension de sortie du moniteur d'hôpital classique par ''graduation'' du signal provenant du moniteur, afin de produire un signal de mesure de pression émulant la sortie d'un détecteur de jauge de contrainte piézorésistif ou d'un pont de Wheatstone. Par conséquent, l'ensemble de cathéter dans son intégralité est conçu pour être utilisé avec n'importe lequel des types courrants de moniteurs hospitaliers. On peut utiliser ledit ensemble de cathéter de contrôle de pression dans toutes les situations nécessitant des mesures de pression très sensibles, et il est possible de le remettre à zéro et de l'étalonner in situ.

Abstract: An electrical rear view vehicle mirror is attached with a mirror carrier (18) to a spherical shell (12) of a shell bearing which has bearing elements (6-16) which have permanent magnets (14, 16) and are attached to a housing (2). As a result, the spherical shell can be held in the bearing elements with a defined degree of holding and sliding friction. Adjustment of the mirror carrier (18) about a centre of rotation (M) is made with the aid of coupling pins (22) on the piston (24), which pins engage on the mirror carrier (18), and by means of two linear motors (20) which are fed with current pulses which are sufficient in each case for the force of the linear motors to overcome the holding friction force of the shell bearing in order to adjust the mirror carrier by a small amount at each pulse. <IMAGE>

Abstract: The microcomputer (12) reads phase difference angle data latched at the leading edge and the trailing edge of a binary logic signal composed depending on the polarity of each phase voltage of an a.c. power supply and compares the phase difference angle data with a predetermined value. Then, proportional plus integral operation is performed about the compared deviation so as to reduce the deviation to zero. The resulting value is sent to an integrating circuit (16) in which the integrating operation is cleared and re-started each time the integrated value reaches a predetermined value. The leading inclination of the integration signal obtained by the integrating circuit changes depending on the value of the input signal. By latching the value of the integration signal at the leading edge and the trailing edge of the logic signal, the phase difference angle data can be modified. As such, if the a.c. power frequency is changed out of a constant state, the microcomputer automatically operates to direct the read phase difference angle to a command value as close as possible and to pick up a signal synchronized with the phase of an a.c. power supply and matched to a predetermined value from the latch circuit (9).

Abstract: A television pick-up tube (1) in an image pick-up system comprises an high-frequency magnetic deflection element (13,L) which deflects the electron beam perpendicularly to the line direction in the television pick-up tube. As a result, residual charge remaining between the image lines on the target face of the television pick-up tube is neutralized (fig. 2b). Inductive coupling (LT1,LT2) of the high-frequency deflection element (13) to the power supply (17) increases the resonance frequency of the deflection element, so that the deflection element can operate at a frequency which exceeds the video signal frequency so that it does not interfere therewith.
